yApplication iled. March 5, 1921'. Serial No. 449,942.

To all lwhen?, t may concern.;

Be it known that I, HARRY E. Rnonns, residing at Toledo, in' the county of Lucas andI State of Ohio,have invented certain 5 new and usefulImprovemen-t's in Means for Preventing the Escape of Lubricant' from Casings, of? which I decla-re the fi'olloiwing tobe a full, clear, and exact description'.

' My invention relates to means for preventing the escape of lubricant-from casings and-has for its object to `JrO'i/"ide improved means otlthis character which is applicable toftransmission gear casings and other forms of housings inc losing various types of mechoperating member projecting therein, with'` improved means for sealing the opening in the wall of the-housing through which the operating member projects, whereby lubrieatingv material within the housing is prevented rom escapin 'through said'opening, With these and ot ier objects in view, the invention comprises certain improved forms of construction,"arrangement of parts and combination of elements whichv will behereinafter more fully described and claimed, it

beingunderstood that the present showing is intended Vto 'illustrate one form of Vthe invention which is susceptible of various modiiications to suit special or varying conditions, and'it willv be further understood thatthe terms which I have used are merely descriptive and not limiting and that it is my intentionto include any and. 'allv modifications which come within the scope of the invention as defined b-y'thelappendedclaims.

rIn the accompanying 4drawings `I'have il- -lustrated' one embodiment. of thel invention in which: Y y l Figure I is: a sectional elevation embodying the invention. -7 n i VFigure' III lis a `fragmentary sectionalfelevation taken on line II.-IIof Figui-eI.

anism whichlmove in oil or lubricant or are l In the kdrivingof vmotorvehicles it has beenifound thatl considerable lubricating material escapes from time totime from the transmission gear shift casingthrough the opening in the extension thereof. in which is mounted theV gear shift lever. This' is an objectionable feature which the present invention is designed to overcome and improved means has been provided i'or sealing thevopening through lwhich the lever pro,- jectsl whereby the escape of oil vfrom the c: sing is prevented, and the possibility of damaging' the .wearing apparel of the occupants or' the vehicle is thus avoided.

`Referring tothe drawings, 10 represents the housing or casing for the transmission gear shift mechanism, said housing being provided with an extension 11 which may be considered as a part of the housing and which isv preferably removably mounted upon the portion 10 of the housing as shown in Figure I. The housing is provided with suitable bearings 12 .for supporting the transmission shaft 13 having the usual driving gears thereon, and the sliding gearl 14 adapted tobe moved by means of the fork 15 yslidably mounted upon the rod` 16, the fork beingmoved by means of the gear shift lever 17 projecting into the housing through the `end wall18 of the extension 11 as shown in Figure I. The. lever is pivoted within the housing upon the pin 19, theopposite ends of which are .supported by the bearings 2O formed in the endL wall of the housing as indicated in Figure II. Thel pin 19 is adapted to be driven out to permit the lever 17 `to be withdrawn froml the housing from time to time. The lever lis providedV at a point, below the pivot 19 with acup or container 2l having aninwardly extending rtubular portion 22which is adapted to be forced upon .the enlarged portion 23 of the lever under pressure, whereby the cup is se.- curely held upon the lever. Projecting into the cup 21 in vspaced relation to the walls thereis an open ended tubular member or sleeve 24, the upper end of which is suitably connected with the end wall 18 of theeXtensionv'll and 4preferably projected through the lopening therein, said sleeve being of a. larger diameterfthan[the diameter of the rodior lever y17 to permit of the desiredv amount of movement of the latter-upon its pivot.. The sleeve is also adapted to be supported bythe pin 19 which extends transcasing through the opening in the extension n thereof; It will be understood that the only escape for the Alubricant from the casingis through'the cup 21 and that any lubricant which may be thrown to the top of the eX- tension 11,y in order to escape therefrom, must first pass into the cup and when the latter is filled any additional lubricant supplied thereto will overflow into the casing,

` whereby the escape of the lubricant through the end wall of the casing is prevented. The extension 1l` is provided with a cover 2G carriedby the rod or lever 17 to protect the i open end of the tubular member 24, the

cover being yieldably heldin engagement with the annular' curved surface 27 of the extension by means of a spring 28 positioned within' the inverted cup-like member 29 secured lupon the lever by any suitable means. lVhile I have illustrated and described one embodiment of my invention, it will be obvious that diii'erent modifications thereof may' be `constructed to` suit diiierent conditions, and I; wish therefore not to be re` stricted or limited to the precise embodiment shown except in so faras the same is limited bythe appended claims.

What I claim as 4new and desireto secure byLetters Patent is: i

3. In a device of the class described, a transmission gear housing, a gear shii'tmeni-v ber project-ing into the housing through `an opening in the wall thereof, and a'cup car` ried by said gear shift member, and having an -opening through which the said member projects, said cup having' a substance therein affording' a sealfor said opening.

4."In' a device of the class described, a transmission gear housing, `a gear shift member projecting into they housing through an vopening in the wall thereof, a container carried by said member within the housing, and a sleeve-like member secured upon the housing andy extending from 'said `opening into the container, said container having la substance therein `affording a sealnfor said opening. j
